Speeds specified in Carbide Create Don't Match Recommended

I just noticed that the default feeds and speeds that Carbide Create uses do not seem to match what the Carbide3D Speeds and Feeds chart indicates. Is this intended or should I update them with the recommended speeds from the chart?

Can you provide us with some examples?

The ones I noticed last night were for the 1/8" and 1/4" endmills for HDPE stock. I don’t have it in front of me but I think the charts state feed rates around 80 in/min and plunge between 20 and 40 depending on the endmill (Note that I use the nomad chart for 1/8" even though I have a Shapeoko 3 XL since the S3 chart is only for a 1/4" mill).

Create states feed rates at 16-ish and plunge rates around 2 if I remember correctly. I can double check them tonight.


Use the faster speeds from the chart
